Benefits of technology

[0011]In another embodiment, an RFID tag that may be positioned inside a metal shell is discussed. The metal shell may be affixed to an object in a hazardous environment. While it is generally understood that metal placed between an interrogator and an RFID tag typically blocks communications with the RFID, according to embodiments of the present disclosure, the shell helps act as an antenna for the RFID tag to allow the RFID tag to be interrogated despite being protected within the metal shell.

Problems solved by technology

Standard RFID tags tend to be fragile and susceptible to cracking at the RFID chip to antenna interface, or within the antenna itself, and are unstable when exposed to elevated temperatures.
This instability does not alleviate the need for RFID tags that operate in extreme environmental conditions.

Embodiment Construction

[0010]Embodiments discussed herein include a radio frequency identification (RFID) chip may be attached to a ceramic film or substrate having an antenna printed thereon to form an RFID tag. The RFID tag may then be positioned in a metal recess and covered with a heat tolerant epoxy. The epoxy fixedly positions the RFID tag within the confines of the metal recess. Despite being within the metal recess, the RFID tag may still respond to interrogation.
